摘要
针对当前面向网络WebGIS的特点,对空间关系运算进行了系统的研究以提供分布式空间分析的需要。采用数据抽取率与运算复杂性两个定性指标来考虑空间关系运算的分布式方案,设计了空间对象关系运算的分布式方案和相应的空间分析Web传输协议。
Based on the characters of spatial relation computation of Network Oriented WebGIS, the authors made a systematic study on spatial relation computation to meet the demand of distributed spatial analysis. The computation complexity and data abstract probability were used to consider the distributed schema of spatial relation computation, and a respective schema and spatial analysis web based transportation protocol were proposed and implemented in WebGIS.
